Key Facts
- —What is happening A Miami-Dade County jury recommended the death penalty on Tuesday, 20 October, for Alberto Sierra, a 42-year-old Cuban-born man who pleaded guilty to murdering his wife and her two young daughters in 2012.
- —Why it matters Florida now allows a death sentence when eight of 12 jurors agree, and the vote on the youngest victim met exactly that minimum, so the case shows how the rule works in practice.
- —The numbers Jurors voted 11 to 1 for death on the murder of Gladys Machado, 12 to 0 on Julia, aged 6, and eight of 12 on Daniela, aged 3.
- —Who is who Sierra is a Cuban-born Miami-Dade resident; Judge Marisa Tinkler Mendez presides, prosecutor Abbe Rifkin sought death, and defence lawyer Khurrum Wahid argued for life without parole.
- —What to watch A hearing on Monday, 2 November, is the defence’s last chance to argue for life before the judge sentences Sierra, because the jury’s vote is only a recommendation.
- —Power Index Cuba ranks 14th of 14 in The Rio Times Latin America Power Index, with 22.5 points (October 2026 edition).
- —What it means for you The case concerns one man’s crimes, not Cuban migration policy, so it changes no rule for Cubans in the United States; readers should watch the Miami-Dade court on 2 November.
A Miami jury recommended death for Cuban-born Alberto Sierra, who admitted killing his wife and two stepdaughters in 2012. The judge has not yet sentenced him.
A Miami-Dade jury recommended death on Tuesday, 20 October, for Alberto Sierra, a Cuban-born man who admitted killing three relatives. The judge will decide the sentence after a hearing on Monday, 2 November.
Sierra, now 42, pleaded guilty on Friday, 7 August, to three counts of first-degree murder, three of kidnapping and other charges. The trial that ended this week decided only whether he gets death or life without parole.
The victims were Gladys Machado, 29, and her daughters Julia, aged 6, and Daniela, aged 3. Their bodies were found in a Miami-Dade home on Tuesday, 13 November 2012.
How the Jury Voted on Each Murder
Jurors voted 12 to 0 for death on the murder of Julia, the elder girl. They voted 11 to 1 for death on the murder of her mother, Gladys Machado.
On the murder of Daniela, eight of the 12 jurors voted for death. Telemundo 51, the Spanish-language station of NBC 6 in Miami, reports that Florida law now requires at least eight.
Florida once required all 12 jurors to agree on death. Telemundo 51 says that changed after a Parkland school-shooting jury split 9 to 3 and the gunman received life in prison.
What Prosecutors and the Defence Argued
Prosecutors argued that Sierra planned the killings and tried to mislead investigators and relatives afterwards. NBC 6 reported on 14 October that Sierra told investigators he suspected Machado of cheating.
Defence lawyer Khurrum Wahid asked jurors to choose life, citing a severe brain injury from a car crash in Sierra’s childhood. In a quote carried by 14ymedio and translated here, he said nobody chooses to fracture their skull at age 12.
The defence also pointed to Sierra’s Cuban mother, an immigrant who raised two sons alone while working two jobs. NBC 6 says Sierra moved to the United States from Cuba in 1996.
What Happens Next in the Sierra Case
The hearing on 2 November is a Spencer hearing, a Florida procedure where the defence can add final evidence against death. After it, the judge sets the sentence, with life without parole the alternative.

What It Means for You
The verdict is about one defendant’s crimes and changes no US law on Cuban migrants, travel or remittances. For readers in the United States, it is mainly a test of Florida’s eight-of-12 rule for death recommendations.
Cuban-born residents of Florida are not affected by the case in any legal way. Anyone following it should look for the court’s decision after the hearing on 2 November.
What Is Not Known
The date of the final sentence has not been reported, and it is not known whether the judge will follow the jury. A defence appeal after sentencing is possible but has not been announced.
NBC 6 gave Daniela’s age as 4 in August, while later reports say 3. The outlets also differ on the home, which 14ymedio places in Little Havana and NBC 6 in northwest Miami-Dade.
The court file and the Florida statute were not opened, so the eight-of-12 rule and the Parkland history rest on Telemundo 51. Sierra’s reported confession and the prosecution’s account were not tested by a trial, because he pleaded guilty.
